Ordering Information
Inset Runway Guard Lights are a series of
alternate-flashing yellow, unidirectional inset
lighting fixtures (L-852G) equally spaced along
a runway holding position marking that are only
visible to aircraft approaching the hold position
from the taxiway side of the fixture. These
unidirectional lights are designed for use in all
weather conditions in autonomous mode.
Features
 ETL Certified
 Low energy consumption Luxeon LEDs
 Long life LED technology, rated at 50,000h L70,
reduces maintenance costs.
 Low profile, <.5˝ (13 mm) – FAA Style 2
 Operates on either 3 or 5 step ferroresonant
CCRs
 Easy to maintain – no sealant required for prism
or feed-through assembly replacement
 Pressure test plug for seal integrity verification
 Can be retrofitted on existing installations
where Logitrac® Control Devices are available.
Requires the addition of a second L-823 plug.
 The autonomous version features an
internal circuitry that eliminates the need for
synchronizing Local Control Devices. Fixture
connects directly into isolation transformer. A
simple, separate Remote Programming Tool is
used to set the fixture to Initial ON or Initial OFF.
The Remote Programming Tool, provided as
accessory, can also be used to program different
parameters.
